Im just more of a top end guy, ive already experienced teh 0-60 whiplash, speeds in my former boosted rx-7's
Hmm what is that turbo? Is that a GT30? Built engine?

Go GT35!!! haven't you seen the comparison dyno sheets? GT35 spools later but more flow makes more power everywhere!

If you really want a GT3071 then just buy my S5.

i cant justify the cost right now! it will either be a 3071, possibly a GT35, i would like more feedback from people that are running the 35 before i make my mind up on that one.

I'm honestly thinking that after this turbo burns itself out, I might look to replace it with a holset hx30/35.

Not pretty.... 5k till full boost (12psi right now) boost starts at 3k though, which isn't too bad.

its a stock catylic -w- a Tsudo exhaust. Going 3" from the turbo back soon at the end of the month.

No, you're pretty much correct. When I had stock exhaust with RB duals I hit 10 psi at about 4800 or so. When I went to 3" all the way I could hit 10 psi around 3500.
